Yes. I haven't tested these apps, but in principle it works because I've done it.
There's two kinds of formats. BDAV and BDMV. BDAV is an mpeg2 only format (from what I can tell) and is old legacy support that might have been dropped
I have both the HD DVD and BD specs on the actual formats (we are members of both), and because of that, we get to write test authoring programs to generate HD DVD and BDMV wrappers around AVC & MPEG2 (& VC-1 too) streams.
The BDMV structure for DVD/R you can derive from AVCHD DVD/R disks burnt by camcorders.
You can burn them onto DVD/RW, except that there's a limit to how high a peak bitrate HD-A1/A2 can play (30Mbps is where is stutters and dies). The PS3 also cannot play anything with peak higher than 54Mbps. The thing to watch out for is that some players don't recognize the AVCHD format, but anyone making AVCHD camcorders : Sony, Panasonic, Hitachi will bend over backwards to support AVCHD or release FW upgrades for it.
AVCHD file structure is basically BDMV.
